The AIDS-stricken Coney Island boy who sexually assaulted four young children, including a 3-year-old boy, in an angry attempt to spread the disease, has pleaded guilty to sodomy, The Post has learned.

The 13-year-old boy, whose identity is being withheld because he is a minor, was 12 when police busted him last December after learning about the attacks, all of which took place on the grounds of the housing project where he lives.

“I got [AIDS], and I want everyone else to have it,” the suspect told detectives, The Post reported at the time.

Sources said the burly suspect – 5 feet and 170 pounds – began his reign of terror two years earlier and told detectives one of his victims, a 9-year-old male cousin, would “do anything I tell him to.”

The youngest victim, a 3-year-old neighbor, has tested negative for the HIV virus, sources said. The health of the 9-year-old cousin and the other two victims, also relatives, is unclear because their families are not cooperating with authorities.

The suspect, who contracted the disease from his late mother, recently pleaded guilty to sodomizing the neighbor, sources said.
